“Cities are basically nonporous environments,” said Beard, the Cornell professor.

Due to the nonporous nature of the watershed, the stream’s depth often increases and decreases rapidly before and after rain, leading the eggs often to be washed out.

It is also nonporous, making it ideal for holding food and sauces without absorbing them.

Given the heavy rainfall and nonporous soil, the waste festers, exposing residents to health risks.

People are unlikely to get the virus by trying on clothing in a store or touching nonporous items like door handles and counters, Popescu said.
